- •
Selenium nanoparticles were stabilized by chitosan of different Mws with different mechanisms.
- •
The morphology of chitosan SeNPs was independent of its Mw after 30 days of growth.
- •
Both chitosan SeNPs showed great stability toward pH changes and enzyme treatment.
- •
Selenium could be released from both chitosan SeNPs due to free radical attack.
